/**
* Returns the number of Transactions at a block number, hash, or tag.
*
* - Docs: https://viem.sh/docs/actions/public/getBlockTransactionCount
* - JSON-RPC Methods:
* - Calls [`eth_getBlockTransactionCountByNumber`](https://ethereum.org/en/developers/docs/apis/json-rpc/#eth_getblocktransactioncountbynumber) for `blockNumber` & `blockTag`.
* - Calls [`eth_getBlockTransactionCountByHash`](https://ethereum.org/en/developers/docs/apis/json-rpc/#eth_getblocktransactioncountbyhash) for `blockHash`.
*
* @param client - Client to use
* @param parameters - {@link GetBlockTransactionCountParameters}
* @returns The block transaction count. {@link GetBlockTransactionCountReturnType}
*
* @example
* import { createPublicClient, http } from 'viem'
* import { mainnet } from 'viem/chains'
* import { getBlockTransactionCount } from 'viem/public'
*
* const client = createPublicClient({
* chain: mainnet,
* transport: http(),
* })
* const count = await getBlockTransactionCount(client)
